Cov theem nrab valence yog tus naj npawb ntawm ions ntawm molecules uas tau sib koom ua ke rau cov hlau ion. Cov theem nrab valency kuj hu ua tus lej sib koom tes. Piv txwv li: Hauv [Pt(NH3)6] Cl4, cov theem nrab valency ntawm Pt yog 6 txij thaum Pt tau koom tes rau 6 ammonia molecules.

Ua raws li qhov no hauv kev xav, dab tsi yog qhov tseem ceeb thiab theem nrab Valency piav qhia?

Cov hlau hauv nruab nrab lossis cov hlau atoms hauv kev sib koom ua ke qhia ob hom valency . Lawv yog cov thawj thiab theem nrab valency . Cov thawj valency muaj feem xyuam rau lub xeev oxidation thiab cov theem nrab valency muaj feem xyuam rau tus lej xov tooj. Tus naj npawb ntawm theem nrab valences yog tsau rau txhua tus hlau atom.

Tsis tas li ntawd, koj yuav suav cov Valency theem nrab li cas? Cov theem nrab valency yog tsau rau ib tug hlau thiab yog sib npaug rau cov coordination tooj. Tus naj npawb ntawm kev sib koom ua ke ntawm lub hauv paus atom / ion tsuas yog txiav txim siab los ntawm tus lej ntawm sigma daim ntawv cog lus tsim los ntawm ligand nrog lub hauv paus atom / ion thiab qhov no muab qhov theem nrab valency ib yam nkaus.

Ntawm no, dab tsi yog Secondary valences?

theem nrab - valence . Noun. (plural theem nrab valences ) (chemistry) nyob rau hauv ib qho kev sib koom ua ke, tus naj npawb ntawm cov ions lossis cov molecules uas tau sib koom ua ke rau hauv nruab nrab hlau ion; nws tus lej sib koom.

Qhov tseem ceeb Valency yog dab tsi?

Cov thawj valency yog tus naj npawb ntawm cov ions tsis zoo uas sib npaug rau cov nqi ntawm cov hlau ion. Qhov thib ob valency yog tus naj npawb ntawm ligands uas txuas los yog sib koom ua ke rau hlau ion.
